ELECTRIC-ARC LAMP.

SPECIFICATION forming part of Iietters Patent No. 267,691, datedNovember 21, 1882.

Application tiled January .'h 18S?.

To all whom it may concern Be it known that l, CHARLES A. HUssEY, of NewYork, in the county and State of New York, have invented certain new anduseful Improvements in Electric-Arc lramps, of which the following is aspecification.

Myimprovements eonsistinavoltaic-arc electric lamp comprising twocarbons or conductors, between which the are is to beformed, means forimpellin g them toward each other, means for connecting them so that onecannot be moved without oecasioning motion in the other, and a stopagainst which one of the carbons or conductors bears, all being socombined and organized that when the carbon or conductor which bearsagainst the stop is arrested by the stop the other carbon or conductoris kept away sufficiently to form the voltaic are. rlhe stop may be ofcarbon or other conducting material, or of any suitable non-conductingmaterial, and preferably will be adjustable, so as to enable the carbonsto come into contact to put out the light. When adjustable anelectromagnet may be employed in the lamp-circuit to actuate it andrender the lamp automatic. rlhe carbons or conductors may beadvantageously arranged at an angle to each other, and supported inrocking bearings. A spring or springs or the equivalent thereof willpreferably constitute themeans for impelling the carbons or conductorstoward each other. The means for connectingthem so that motion in onewill occasion motion in the other may consist ot' gear-wheels. Thengear-wheels are employed one is preferably made adjustablecireumferentially on its shaft to provide for maintaining the carbons orconductors at different distances apart.

The improvements further consist in a novel construction of an electriclamp, whereby the base-plate, earbons, their appurtenances, and valsothe globe may be detached conveniently.

1n the accompanying drawings, Figure 1 is a perspective view of anelectric lam-p embodying my improvements. Fig. 2 is a view of theessential parts ot' the same on a larger scale. Fig. 3 is a plan ofthese parts on the same scale. Fig. 4 is a section of the lower portionof the cowl of the globe. Fig. 5 is a (No niodcLl view illustrative ofthe means whereby the base-plate ofthe lanip is supported. Fig. Gis asectional view of these means. Figui' is also a sectional view of thesemeans. Fig. S is a detail view,illustrative of au adjustable gearwheel,which is combined with the carbons. Fig. 9 is a view illustrative ot'means which may be employed for separating the carbons to start thelamp. Fig. 10 is a sectional view ot' the same, taken in a plane atright angles to that ot' Fig. 9; and Fig. ll is an inverted plan ofthese means.

Similar letters of reference designate corresponding parts in all theiigures.

A B designate two earbons, which are shown as of semi-cylindric shape,but may be of any other suitable forni. They are secured in sockets orholders A B', which are mounted on rotary shafts AZ B2. rlhe sockets orholders which I have shown consist each ot' two jaws, between which thelower end of a carbon tits, and, a set-screw passing through one of thejaws and impinging against the carbon, so as to clamp it against theother jaw. Applied to the shafts A2 B2 are spring-sA3 B, which tend torotate the shafts in such directions that they will carry the upper endsof the carbons into proximity with .each other. On corresponding ends ofthe shafts A2132 are pinions A" B4, with which engage two gear wheels, CD, that also engage with each other.

It is obvious that each of the springs As B3, in acting to rotate theshalt to which it is ap plied, also serves, through the agency of thesepinions and gear-wheels, to rotate the other shaft in the oppositedirection, and consequent ly to impel the carbons toward each other. Forthis reason I do not confine myself to the luse of a separate spring foreach of the shafts.

l will here remark that I do not desire to be restricted to the use of aspring or springs for inipelling tbe carbons toward each other, for Imay tind it advantageous to use a weight or weights or other equivalentdevices.

I.lhe shafts A2 BZ and the shafts supporting the gear-wheels C D, aresustained in bearings extending from metalplates P P P2, which areconnected to a base-plate, I, of hard rubber or other insulatingmaterial.

Between the pinions A4 B4 and their shafts A2 B2 are placed bushings a bof hard rubber or other suitable insulating material, so that thesepinions and the gear-wheels G D will not make a short circuit in thelamp. The bushing I), which is applied to the shaft B2, (seeparticularly Fig. 8,) has a iiange or shoulder at the inner end, and thebody or main portion does not extend as far forward as the pinion B4,which tits on it. In front of the pinion there is arranged on the shafta washer, b. A shoulder on a hand-screw, c, which is screwed into theend of the shaft, bears against this washer and serves to clamp thepinion B4 between it and the shoulder on the bushing, thereby securingthe pinion in position on the shaft. The bushing b is prevented frombeing` forced backward on the shaft through the action of the screw bymeans of a shoulder on the shaft against which it bears. By looseningthe screw the pinion may be adjusted on the shaft circumferentially, andby tightening the seres7 again the pinion will be retained in theposition to which it is adjusted. rIhe importance of this feature willappear presently.

E designates a device against which and near its tip the tip of thecarbon B rests. It

lserves as a stop for limiting the motion of the said carbon toward thecarbon A. It is made in the form of a narrow strip and occupies avertical position, as here shown.

rPhe pinions and gear-wheels are so combined with the shafts A2 B2 ofthecarbon-holders A B that when the tip of the carbon B comes in contactwith the stop the tip of the carbon A will be kept sufficiently away toform the voltaic arc. By adjusting the pinion Bl on its shaft thedistance between the tips of the carbons may be varied to suit electriccurrents of different electro-motive force.

The stop E may be made ot' kaolin or other suitable non-conductingmaterial or it may be ot' carbon. When made of carbon it and the carbonB, which is in contact with it, will together equal in bulk the bulk ofthe carbon A, providing thelam p is supplied with alternating currentsof electricity. If, however, the lamp is supplied with a direct current,the carbon B and the carbon-stop E may forni the positive electrode, andthen they will together have double the bulk of the carbon A, so thatequal lengths of both the carbons A B will be consumed. As the carbons AB are consumed the stop Eis correspondingly burned away. Hence thecarbon B is constantly impelled inward, and the carbon A has acorresponding movement, so as to preserve the relation between its tipand the tip of the carbon B. The rapidityof the feed or movementof thecarbons toward each other varies correspondingly to the consumption ofthe carbons.

The stop E is secured to a holder, E', consisting of twojaws, betweenwhich the stop fits, and set-screw inserted in one ot' thejaws, andadapted to impinge against the stop and secure it. The holder E isprovided with a shank, E2, which extends through a tube, P5, fitted inthe base-plate, and is provided with a hand-piece, E3, of insulatingmaterial. A screw, g, inserted in this tube and entering a longitudinalgroove in the said shank, serves to guide the stop, when adjusted, andalso to clamp it in position. By loosening this screw the stop may belowered to permit the carbons A B to come together and put out thelight, and by raising the stop and securing it in position by the saidscrew the carbons may be separated, and the voltaic are established.

The circuit-wires G G of the lamp extend down through a supporting-rod,H, to and thence through two arms or hangers, II, which dependtherefrom. At thelowerend they have attached to them metalliccontact-pieces, I, which complete the circuit to the plates P P. Thesecontact-pieces are not fastened to the said plates, but simply bear onthem. rIhe circuit is continued through these plates and thence to theshafts A2 B2, the carbon-holders A B', and the carbons A B.

In Figs. 9, l0, and Il I have shown an electromagnet, J, introduced intothe circuit for the purpose of operating the stop E. In this example ofmy invention the plate P is divided into two parts, which are insulatedfrom each other by their attachment to the base-plate.

The electric circuit extends from that part ot' the plate I on which oneofthe contact-pieces I bears to the wire of this electro-magnet, andfrom the wire ofthe electro-magnet to the other part of the plate P, andthence the circuit is continued, as before described. The armature oftheelectro-magnet is connected to a lever or levers, K, and the latter neartheir free ends are connected to a lever or levers, L, close to thefulcruni of the latter. The levers L are connected with the shank of theholder in which the stop E is secured. When the electric current issupplied to the lamp the electromagnet is energized, and, attracting itsarmature, raises the stop E into an operative position. When theelectric current ceases the electro-magnet releases its armature, andthe stop descends so as to permit the carbons A B to come together. Iemploy compound levers, so that the armature of the electro-magnet canimpart the requisite motion to the stop.

M designates a globe of glass or other suitably translucent ortransparent material. To its lower end a metal ring, 7L, is secured bymeans of screws t' lapping over a lip with which the lower end isprovided.

N designates hooks, which are hinged to the lower ends ofthe arms orhangers H', and are adapted to be engaged with the globe-ring It, so asto support it and the globe. By swinging the hooks inward the globe-ringwill be released from them, and it and the globe may be passed downwardover them and so removed. The base-plate P4, when in place, bearsagainst the lower side of these hooks and precludes their displacement.On the base-plate are lugsj, which are provided with screws k, that IISby overlapping the globe-ring h secure the baseplate in place. As thecontactpieces I are not fastened to the plates I P the baseplate and itsappurtenances can be removed at any time by loosening the screws L', andit may be easily replaced when desirable.

O designates a cowl for the globe M. It may be made of sheet meta-l andof any desired form. As here shown it is adapted to slide up and down onthe rod I-I.

It will be seen that by my improvements I produce a very simple anddesirable lamp.
